Outer Limits 4x4 Board

So just brought my first 4wd. 1993 landcruiser (not sure but would be either gx or gxl, is a very basic model).

First thing i noticed is when pressing the rear demister switch, the back wiper turns on. Took the trip off and found that a wire had been removed from an empty plug and put to another wire. After removing this neither the demister switch or the controls on the stalk would work.

Basically looking for a wiring diagram to tell me whats supposed to go where.

Any help appreciated

thanks in advance
